Lima, who announced her pregnancy this week and already has a 2-year-old daughter with hubby Marko Jaric, recently helped launch a new lingerie line for Victoria's Secret, where she stepped out in a sexy white mini.

No big baby-bump reveal there, but the supermodel did flash her gorgeous glow, which we expect will only get more blinding over the next few months.

On the other hand, Ambrosio—who has a 3-year-old daughter with fiancé Jamie Mazur—is about seven months along and was spotted yesterday in L.A. rocking a breezy red dress that flattered her blooming figure and an ASTARS Nashville Jacket in White Swan.
